I have recently become a vegetarian ( been 1 month) and I noticed when I eat alot of cheese or maybe butter I get sick. A couple weeks ago my mom made homemade Mac & cheese I ate it then got sick. The other morning I ate an egg and cheese sandwich and then got sick. Today I ate pizza and garlic bread and got sick. My parents seem to think its because im not eating meat, I'm just wondering of this is normal when stop eating meat?
